Ive heard subs express appreciation for doms in the past as much as the other way around. While it is true that subs have reasons to appreciate doms, the whole arrangement between the two is one that inherently favors the dom more. Heres why. (this applies to slaves too)
Subs are basically always the more selfless one. While part of the reason theyre subs is built into who they are, they also generally wish to please the dom. More on what I mean shortly
Meanwhile, doms dont have to really care about their subs. Unlike subs, everything that comes from a dom is based on self interest. Being a dom is easy compared to being a sub. They get to act upon a desire to hurt people as sadists, meanwhile masochist subs may enjoy pain, but pain is still pain. It’s still unpleasant on some level. Plus, many subs engage in activities outside their comfort zone where they dont benefit at all, simply because their dom wants them to.
This is accentuated in slave/master dynamics. Slaves do everything for their master and the price the master pays for such a thing is far lower than its value.
This is why subs are so wonderful. Not just because theyre selfless, but because BDSM is a deal which inherently favors the dom, and we still have subs to begin with anyways.
Subs, youre awesome. Us doms love you (for more than one reason).
